Best Bike Split

Best Bike Split is a race-planning and optimization platform built for cyclists and triathletes who want to turn power data and course details into a realistic, executable bike strategy. At its core is a math-and-physics engine that predicts how you’ll perform on a specific route and then generates a power-based pacing plan designed to produce your fastest possible split under the conditions you expect on race day.

To get started, you create an athlete profile with key inputs such as weight, height, FTP, and bike type. Next, you choose an existing course or build your own. Best Bike Split models the course profile and continuously accounts for major performance drivers—such as aerodynamic drag (CdA), rolling resistance, and mechanical losses—so the plan isn’t just a generic pacing suggestion. You can also layer in weather and environmental factors, helping you understand how temperature, wind, and other conditions may affect your predicted time and the power you’ll need to hold.

The output is an optimized plan you can use to guide race execution: target power guidance tailored to the terrain, plus a clear prediction of expected performance. Afterward, it can be used to compare your planned strategy against what actually happened, making it easier to learn from past races and refine your future pacing. Whether you’re aiming to nail a triathlon bike leg without compromising the run or trying to pace a challenging cycling time trial efficiently, Best Bike Split provides a structured, data-driven approach to planning and analysis.

The platform is available online, with account creation and member login, and offers subscription options for athletes who want deeper capabilities and more planning flexibility.
